"An Analysis Of Francis Schaeffer’s “The Church At The End Of The 20th Century”
"Francis Schaeffer has been characterized as an Elijah to the late twentieth century. Though not as inspired in the same direct sense as his Biblical forebears, Francis Schaeffer did articulate a vision of the future remarkable in its accuracy and a message startling in its relevancy. Schaeffer was able to accomplish this by extrapolating from the cultural situation of the late 1960’s and early 1970’s and projecting these trends into the future where the implications of these assumptions would have the time necessary to fester over into a comprehensive dystopian milieu. Schaeffer’s “The Church At The End 20th Century”, from a standpoint a tad less than nearly a half century in the past, explored a world not unlike our own where Western society has abandoned its Judeo-Christian foundations and stands poised to lose not only its order but also its liberty as a consequence."
Schaeffer was interested in the Counterculture of the sixties. He died in May of 1984 and the Counterculture years were mostly from 1962 until 1980. I corresponded with him briefly in 1983 when he was working on his last book, The Great Evangelical Disaster. I had found resistance to my manuscript on the Counterculture from conservative Christian book editors. Schaeffer said he understood what I was wrestling with.
I used the writings of three social scientists on the Counterculture, Herbert Hendin. The Age of Sensation, 1975, Christopher Lasch. The Culture of Narcissism: American Life In An Age
of Diminishing Expectations, 1978, and Daniel Yankelovich. New Rules: Searching for Self-Fulfillment In A
World Turned Upside Down, 1981. From these authors from my my own experience with the Counterculture in Madison, Wisconsin I found a number of traits of people in the Counterculture, and grouped these traits into four general categories to describe the Counterculture. These General Traits were Selfishness,he Revolt Against Christian Morality. the Lowering of Man to His Desires, Feelings and Conditioning, and The Denial of Objective Reality. I also used scripture to characterize and criticize the Counterculture.
The book was self-published, but was distributed by a mail order Christian outfit. At the time I wrote the book I was not aware of the role of the Frankfurt School Marxists in their helping to create the Counterculture. I did know then that Theodore W. Adorno in his 1950 book, The Authoritarian Personality had used questionnaires - the F Scale especially - to claim to measure the potential of people for following fascism and authoritarianism.
Wikipedia at
https://en.wikipedia.org/wiki/Eros_and_Civilization says "Eros and Civilization: A Philosophical Inquiry into Freud, 1955, is a book by the German philosopher and social critic Herbert Marcuse, in which the author proposes a non-repressive society and attempts a synthesis of the theories of Karl Marx and Sigmund Freud......Eros and Civilization has been compared to books such as Norman O. Brown's Life Against Death (1959). Eros and Civilization helped shape the subcultures of the 1960s."
"The Marxist writer Paul Mattick reviewed Eros and Civilization in Western Socialist, writing that Marcuse "renews the endeavor to read Marx into Freud", following the unsuccessful attempts of Wilhelm Reich.[4] Brown, a classicist, commended the work in Life Against Death (1959), calling it "the first book, after...Reich's ill-fated adventures, to reopen the possibility of the abolition of repression."
But wikipedia does not make it clear that Herbert Marcuse was a major member of the Frankfurt School and one of the Marxists who came to the U.S. and became highly influential university professors.
The Frankfurt School Marxism influenced the Counterculture not only through the New Left which was allied with the Counterculture but also Herbert Marcuse of the Frankfurt School had an influence upon the Hippie and LSD drug movement, which in the sixties, was a big part of the Counterculture. The Hippies were interested in drugs, an anti-Christian attitude and sex.
The sexual liberation movement of the sixties - in the watering holes of the Counterculture, the Haight- Ashbury, The Lower East Side and on the campuses at Madison and Ann Arbor - was a stepping stone to Transformational Marxism. Some would say that the sex lib movement was part of Transformational Marxism and that the Second Wave Feminism which got going by 1969-1970 in the Counterculture was Marxist.
Anyway, Transformational Marxism of the Frankfurt School got going in the United States during the purple decades of the Counterculture. And Francis Schaeffer knew before he died that the Counterculture was to change the culture of the country.
Remember - Selfishness,the Revolt Against Christian Morality. the Lowering of Man To His Desires, Feelings and Conditioning, and the Denial of Objective Reality were themes of the Counterculture in the sixties and seventies while Schaeffer was alive.
